Benefits of technology

The patent describes a spine implant system for an anterior lumbar interbody fusion surgical procedure. The system includes an ALIF cage and anchoring members that are inserted into a vertebral space and directed into the vertebral bone. The cage has a porous body with a central cavity and an anchoring member retention component for holding the anchoring members. The anchoring members can be curved or linear and can be attached to the cage using a set screw or plate. The system also includes an inserter for holding and directing the anchoring members into the cage. The inserter has curved channels for each anchoring member and a leaf spring to retain them. The cage can also have a pivoting anchoring member retention component that can cover the inserted anchoring members to prevent them from coming out. The invention provides a reliable and effective system for spine surgery.

Embodiment Construction

[0042]Referring to FIGS. 1-9, there is depicted a form of an anterior lumbar interbody fusion (ALIF) implant (ALIF spine implant or ALIF implant), generally designated 10, fashioned in accordance with the present principles. The ALIF implant 10 is made from a biocompatible material such as, but not limited to, PEEK, PETE, other plastic or polymer, titanium, stainless steel, an alloy of titanium or stainless steel, or otherwise. Preferably, but not necessarily, the ALIF implant is 3-D printed. The ALIF spine implant (spine implant) 10 has a porous cage or interbody device 12, two or more anchoring members 14, each anchoring member 14 fashioned as a barb, blade, shim or the like (herein “barb”) 14, and a set screw (anchoring member) 13.

[0043]The set screw 13 is generally cylindrical with external threads. A socket 15 is provided in the top of the set screw 13 that is configured to receive a tool (not shown) for installing the set screw into the porous cage 12. As seen in FIGS. 2-4, th...

Abstract

ALIF spine implants, ALIF installation instruments / tools, and ALIF procedures using the present ALIF implants and present ALIF installation instruments for an anterior lumbar interbody fusion (ALIF) surgical procedure are provided. The ALIF implants are characterized by an ALIF cage and anchoring members. The ALIF installation instruments are characterized by a shaft having an inserter on one end that receives and holds an ALIF cage and anchoring members. The installation instrument allows insertion of the ALIF cage into a vertebral space, the anchoring members to be received in the ALIF cage, and then into vertebral bone. The ALIF cage is preferably, but not necessarily, 3-D printed having a central cavity, an end configured to accept a plurality of anchoring members and direct a portion of the anchoring members up and out of the cavity, a cutout configured to receive an anchoring member retention component, and an anchoring member retention component.
